Patented Dec. 14, 1943 UNITED STATES PATENT OFFICE wmnow Clara A. Bowron, Meadow Lane, Conn. Application December 19, 1942, Serial No. 469,534 (01. 160-90) Claims.

This invention relates to windows, and particularly to a window construction of the type in which a window sash serves both as a screen sash and as a storm sash.

When multipane window sashes are employed in the windows of houses and other buildings, and particularly when the windows are of the double-hung sash type, it is usual, when providinga screen or a storm sash for such windows, to 'provide'a singlesash for the entire window opening. In the case of the storm sash, this is usuallydivided by mullions into two or four large panes. Ordinarily, separate removable screens and storm sashes are provided, each of which requires storage room when not in use.

1 One of the principal objections, however, to windows'of this type is that the mullions of the storm sash do not comeopposite the mullions of the main window sash or sashes and therefore it is obvious that there are two glazed sashes, one.

behind the other in each window frame. Furthermore, by reason of the light reflection from the panes of the two sashes, that is, the reflection from the main window panes to the storm pane or panes and back, it is somtimes difficult to see through such windows clearly on a bright day or even on a .dull day. This further emphasizes the double window effect. Even when the storm sash is provided with the same number of panes and mullions as the main sash or sashes there is no one position from which the window can be viewed and have these mullions all register.

An object of the present invention is to provide a window construction of a more or less permanent nature which will overcome the objectionable appearance of the present arrangement of permanent window sashes and removable sash opening. In this way, when looking through the window as it will appear for the warmer part of the-year, one will get the distinct impression of a multipaned sash but without the impression of a second sash behind the first. When the outer sash of a window thus constructed is to serve as a storm sash, the invention contemplates covering one face of the outer sash with a single sheet of glass which will cover all the individual openings or lights in the sash, leaving the screen sections which now fill the light openings as a permanent part of the outer sash.

, An important advantage of the sash and window construction of the present invention is that,

when the storm pane has been added to the outer sash of the double sash window, there still is no objectionable non-registering mullion effect and also no objectionable double reflection effect, this latter effect being effectually broken up by the interposition of the screens in the sash openings.

which are left permanently in position between the storm pane and the pane of the inner sash.

' to the ordinary American type of double-hung storm: sashes while at the same time it makes possible the equivalent of full storm sash protection as well as full screen protection.

Theinvention aims flirther so to improve window construction that substantial protection will be provided both against injury to the glass of the window and also against burglarious" entrance. To this end the invention aims to provide, as a permanent part of the window installation, two sets of window sashes, the inner one or ones of which will be undivided by mullions and will carry the window pane or panes of plate glass or other suitable glass, and the outer one or ones of which will be divided by mullions, but, instead of carrying panes in the multiple sash openings thus provided, will carry, as a part of its permanent structure, a wire screen in each window sashes and when incorporated in such window constructions makes possible the contenient and easy installation and removal of the storm panes, particularly in the upper windows of a building, since all of this may easily be done, with the construction of the present invention, from the inside of the building.

With the foregoing and other objects in view, some of which, together with important features of the invention, will appear more clearly when the following description and claims are con- I sidered in connection with the accompanying drawing, the invention is herein shown as embodied in a window construction of the doublehung type. In the drawing,

- Figure 1 is an elevation viewed from within the room of a double window of the double-hung type embodying the present invention;

Figure 2 is a section on the line 2-2 of Figure 1; I

Figure 3 is a section on the line 3-3 of Figure 1, and

Figure 4 is a section on the line l4 of Figure 1.

As herein shown, the inside double-hung win-- dow may comprise an upper sash 2 and a lower sash l of ordinary construction, these sashes preferably having no mullionsand being glazed each with a single sheet 8 of plate glass or other suitable glazing. The frame 8 in which the grooves ll of the upper sash Ii for asaaeaaf v n a st upper storm pane 20 in position in this jsash'or removing it therefrom. Likewise. by merely lowsashes 2 and 4 are hung may be of any standard construction.

Outside the double-hung window just described is a second double-hung window comprising an upper sash l and a lower sash I2 of ordinary construction, these outside sashes l0 and I! being, however, provided with mullions I4 dividing each sash into a plurality of lights, for example, six lights each, as shown. Instead, however, of glazing the light openings formed by the mullions and sash, each light opening is provided with a screen section l6 of suitable mesh and material to form an insect screen through which light win. readily enter .and which will preferably resist. corrosion such, for example, as bronze screening. The insect screen will befastened in the light openings in the positions in the sash usually occupied by panes of glass.

From the description so far it will beseen that,

- when looking'through the window, either from the outside or from the inside, with the parts in the'position shown in Figures 1 and 2, the

'overall effect will be that of a window having six lights in each sash. the mullions in the outer 1 sashes l0 and I2 serving to give the six-light efiect also to the inner sashes 2 and 4 even though they are glazed with a single sheet. a

From the description so far it will be seen that the outer sashes l0 and [2, which may be left I permanently in position, serve as insect screens,

also as screens to protect the large-pane B of the inner sashes from injury by hailstones or other 'hard substances that might otherwise come in contact therewith, and that they also serve to some extent to prevent burglarious entrance to the house by increasing the difiiculty of entering through the windows.

ezing the upper sash 2 of the inner window, access is had to the grooves I8 for inserting or removing the storm pane" in the low'ersash- II of the outer window. It willalso be seen that, when not in use, the storm panes will require very little storage room.

Among the important advantages of the present invention, as hereinabove pointed out, are I the fact that a simple combined screen and storm window construction is provided which permits simple glazing of both the inner and outer sashes from the inside or the outside.

Although the invention has been herein shown and described in a double-hung window embodiment, it will be understood that many o-f its advantages can be obtained in other types of window construction.

The outer sashes I0 and I2 also have the fur- ,ther purpose of serving as holders for storm win- This is accomplished by providing each dows. I sash with retaining means I8, such as angular metal strips forming guides or sockets for storm panes 20, the guides l8 comprising side members 'and a bottom member and being open at the top to permit the storm panes 20 to be installed by slipping in at the top and to be removed by simply liftin them out of the guides. To protect the storm panes 20 and also those who handle them, they are preferably provided on their edges with metal binding strips 22. Also to insure i an air tight fit at the top, any suitable weather stripping may be provided, such as a flexible rubber strip 24, secured in position by a turned over part 26 of the upper binding strip 22.

The storm pane 20 for the lower sash, instead of being placed upon the outer face thereof, as,

is the storm pane 20 for the upper sash Iii, may

be received in a guide or socket i8 on the inner "face of thesash. This prevents the necessity for cutting a slot inthe upper rail 28. of the lower sash l2 to receive the storm pane.

From the foregoing description, it will be seen that the storm panes 20 may be put into position to complete storm window protection for the winter withoutremoval of anysash and without the necessity of going outside the building in which the windows are located. By lowering both the inner upper sash 2 and the outer upper sash ill of the window construction, accessis had to the position, and the sash carrying said screening What I claim asnew is:
